As the infection of the new coronavirus spreads, the efforts of Okinawa Institute of Science and Technology Graduate University (OIST) are a hot topic.
For example, Associate Professor Mahesh Bandy, who heads the Non-equilibrium and Non-Equilibrium Physics Unit, has developed a unique method for making masks that block virus particles with a charged layer, such as the "N95 Charged Filter Mask." By applying voltage to the "cotton candy making machine" using a car battery, pouring crushed powder from a PET bottle instead of sugar, and rotating it, a charged nanofiber dough can be made.With this, it is possible to create a face mask of the same level as medical use using only general materials.
An alcohol gel supply project called "OIST gel" is also underway.Using isopropanol as a raw material, OIST researchers and volunteers from other departments will make gels, bottle them, and even design labels.It is said that it aims to produce at least 400 liters, and it will be donated to local Onna village and high-risk places in Okinawa prefecture.
In addition, a research team consisting of a mathematical mechanics and materials science unit and a micro-bio-nanofluid unit will produce a 3D printed face shield, and a team of femtosecond spectroscopy units will use ultraviolet C-wave (UVC) lights for masks. Designed and built a sterilizer.Face shields will soon be ready for distribution to hospitals in Okinawa.The first few sterilization units have been delivered to a hospital in Naha City, and construction is currently underway.
These projects, which utilize the expertise of OIST researchers, are a solid contribution to the local Okinawa.
